Struct Operator 

pub struct Operator<const C1: char, const C2: char = '\0', const C3: char = '\0', const C4: char = '\0'>;

Operators made from up to four ASCII punctuation characters. Unused characters default to \0. Custom operators can be defined with the crate::operator! macro. All but the last character are Spacing::Joint. Attention must be payed when operators have the same prefix, the shorter ones need to be tried first.

Implementations

impl<const C1: char, const C2: char, const C3: char, const C4: char> Operator<C1, C2, C3, C4>

pub const fn new() -> Operator<C1, C2, C3, C4>

Create a new Operator object.

Trait Implementations

impl<const C1: char, const C2: char, const C3: char, const C4: char> Clone for Operator<C1, C2, C3, C4>

fn clone(&self) -> Operator<C1, C2, C3, C4>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<const C1: char, const C2: char, const C3: char, const C4: char> Debug for Operator<C1, C2, C3, C4>

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<const C1: char, const C2: char, const C3: char, const C4: char> Default for Operator<C1, C2, C3, C4>

fn default() -> Operator<C1, C2, C3, C4>

Returns the “default value” for a type.

impl<const C1: char, const C2: char, const C3: char, const C4: char> Parser for Operator<C1, C2, C3, C4>

fn parser(tokens: &mut TokenIter) -> Result<Operator<C1, C2, C3, C4>, Error>

The actual parsing function that must be implemented. This mutates the tokens iterator directly. It should not be called from user code except for implementing parsers itself and then only when the rules below are followed.

impl<const C1: char, const C2: char, const C3: char, const C4: char> PartialEq for Operator<C1, C2, C3, C4>

fn eq(&self, other: &Operator<C1, C2, C3, C4>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<const C1: char, const C2: char, const C3: char, const C4: char> ToTokens for Operator<C1, C2, C3, C4>

fn to_tokens(&self, tokens: &mut TokenStream)

Write &self to the given TokenStream.

fn to_token_iter(&self) -> TokenIter

Convert &self into a TokenIter object.

fn into_token_iter(self) -> TokenIter

where Self: Sized,

Convert self into a TokenIter object.

fn to_token_stream(&self) -> TokenStream

Convert &self into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self into a TokenStream object.

fn tokens_to_string(&self) -> String

Convert &self into a String object. This is mostly used in the test suite to compare the outputs. When the input is a &str then this parses it and returns a normalized String.
